Stealin catchin middle pair, face turn raise, drawsy board, vs unknown

[Cerril]

Probably call the turn and any nondiamond/nonace river, but I can't say I'm a winning player in these situations

Another question I'd be curious about is what to do as a villain with 9x (x nonpair higher than 9) or two diamonds with a 7 or 9 on this board and hero's actions (hero obviously couldn't have 7d in the Xd7d case)
